Specification of Letters Patent.

Patented Feb. 9, 1909.

Application filed. February 5, 1908. Serial No. 414,433.

To all whom 'it may concern:

Be it known that I, EDWARD DAVIS, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Dispensing Apparatus, of which the following is a specification.

This invention relates to apparatus for dispensing liquids in measured quantities or charges, and it has for' its chief object'to provide means whereby liquids may be conveniently dispensed and accurately measured, and also whereby the number of charges dispensed may be accurately registered toprevent fraud on the part. of dishonest employees in the dispensing of liquids, and particularly spirituous and other beverages.

To this end, the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this spec1ficat1on,Figure 1 represents a side elevation of a dispensing apparatus embodying my invention, a portion of the apparatus being shown in section. Fig. 2 represents a section on line 22 of Fig. 1, showing two pairs of receptacles. Fig. 3 represents a partial plan view of the apparatus, also showingtwo pairs of receptacles, portions of the casing thereof be mg shown in section on line 33 of Fig. 1.

"Fig. 1 represents a section on line 4-4 of Fig. 8. Fig. 5 represents a section on line 5-5 of Fig. 4. Fig. 6 represents a fragmentary sectional view of one of the valve casings, showing the preferred arrangement of liquid-conducting ports therein. Figs. 7 and 8 represent different side elevations of the liquid-controlling valve shown in section in Figs. 4 and 5. Fig. 9 represents a section on line 99 of Fig. 1. Fig. 10 represents a section of line 10-10 of Fig. 4. Figs. 11, 12, 13, 14 and 15 represent views of different parts of the registering mechanism.

The same numerals of reference indicate the'same parts in all the figures.

The preferred embodiment of my invention includes two measuring receptacles 12 12, located side by side, and connected as hereinafter described, 'to constitute a pair, one receptacle of the pair being adapted to be charged while the other is being discharged. The receptacles are here shown as elongated cylinders supported by a suitable frame 13, each receptacle being somewhat inclined, so that one end is lower than the other to permit the discharge of all the contents of the receptacle. The supporting frame includes a member formed a passage 15 communicating with a source of liquid supply, which is preferably the primary tank 16 hereinafter described, and twofiow passages 17 17 which communicate with the lower portions of the reservoirs 12, each flow passage being adapted to con duct liquid into the accompanying receptacle to charge the same, and out of the receptacle to discharge it.

18 represents a frame member which is rigidly afiixed to the member 14, and constitutes a valve casing having a valve chamber 19 in which is rotatably mounted a plug valve 20. The casing 18 has an inlet 15 which registers with the passage 15, and two flow ports 17 which register with the flow passages 17. In the periphery of the valve 20 are formed two oblique connecting passages 21, each of which is adapted to register at its upper end with the inlet port 15 and at its lower end with one of the flow ports 17 the arrangement being such that when the valve is turned to one position, one of the connecting passages 21 will connect the inlet port 15 with one of the flow ports 17, and permit the flow of liquid from the receptacle 16 to one of the measuring receptacles 12. When the valve is turned to another position, the other connecting passage 21 connects the inlet port 15 with the flow passage 17 leading to the other measuring receptacle. The valve 20 therefore has two connecting positions, one of which causes the filling or charging of one measuring receptacle, while the other causes the filling of the other measuring receptacle. The valve 20 is provided with a discharge passage 22, which is located between the lower ends of the connecting passages 21, and is arranged to coincide alternately with the flow ports 17, the lower end of said discharge passage communicating with a permanently open discharge spout or nozzle 23 at the lower end of the valve casing 18. The arrangement of the discharge passage 22 relatively to the connecting passages 21 is such that the discharge passage registers with one of the flow ports 17 whenthe valve is in each of its connecting. positions, so that the measuring receptacle Which has been prevlously charged and 1s not connected by a connecting 14, in which ispassage 21 with the inlet port, is connected by the outlet passage 22 with the permanent outlet 23, and is discharged while the other measuring receptacle is being charged. The operation of the apparatus may therefore be practically continuous; that is to say, the measured charges may be delivered through the outlet 23 in rapid succession, a tilled measuring receptacle being ready for a (lischarge as soon as the companion measuring receptacle has been discharged.

An important feature of my invention consists in the utilization of the movable valve 20 as a member of a registering mechanism adapted to register or indicate the exact number of movements of the valve, and therefore the number of charges dispensed by the measuring receptacles. To the valve is rigidly affixed a gear segment 25 which moves with the valve,-the latter being provided with a handle 26 here shown formed in the same piece or part with the segment 25.

27 represents a pinion meshing with the segment 25, said pinion being mounted to rotate on a suitable fixed pintle 28 in the casing of the machine. The pinion is provided with a substantially integral crank arm 29, which is connected by link 30 with a swinging U-shaped yoke 31.

32 33 34 represent numbered disks, which are arranged concentric with each other, and are rotatable independently, said disks be ing numbered as shown in Fig. 9, the disk 32 representing units; the disk 33, tens, and the disk 3%, hundreds. To said disks are affixed, respectively, shafts 32 33 3%, which are concentrically arranged as shown in Fig. 4, the shafts 33 34: being tubular, while the shaft 32 passes through the inner tubular shaft To each of said shafts is aff xed a ratchet gear 35, there being three of said gears, and each being proviced with ten teeth. The outer tubular shaft 3% is journaled in a fixed bearing in a plate 37 forming a part of a casing in which the registering mechanism is located, said tubular shaft 34 constituting a bearing for the tubular shaft 33, which in turn serves as a bearing for the shaft 32. The upper arm of the yoke 31 is mounted to oscillate on the outer tubular shaft 3 f, while its lower arm is mounted to oscillate on the lower portion of the inner shaft 32. The yoke is provided with dogs 38 enga 'ing the ratchet gears 35,

g as shown in Fig. 10, there being one dog 38 for each gear, said dogs being mounted to oscillate upon a rod 39 afiiXed to the arms of the yoke 31. Springs 40 are provided for holding the dogs yieldingly in engagement with the ratchet wheels 35, as shown in Figs. 10 and 14. The units and tens gears are provided with a flange ll, which is of greater diameter than the teeth of the gear, and is provided between two gear teeth with a notch d2 (Fig. 11). The described registering mechanism is so organized that each movement of the valve 20 imparts an oscillating movement to the yoke 31. From the yoke a step-by-step rotation is imparted to the units shaft After a complete rotation of this shaft, this movement is imparted through the described mechanism, to the tens shaft, which is moved one step. After the step-by-step movement of the tens shaft has resulted in a complete rotation thereof, it imparts in like manner a single step relation to the hundreds shaft. Provision is thus made for registering any number of discharges up to one thousand, and it will be obvious that by increasing the number of elements of the registering mechanism, a larger number can be registered. The arrangement of the registering mechanism is such that the register operates before the valve reaches the position to discharge liquid, so that fraudulent discharge of liquid without operating the register is impossible. The register is inclosed in a suitable, casing, which is provided with a removable cap or cover 4t3, which is automatically locked with the casing, and can only be unlocked by the employment of a special key ll (Fig. 14), so that tampering with or unauthorized access to the register prevented.

I have here shown the primary receptacle 16 provided with an inlet 4-7:, which may be connected by a flexible or other tube ll) with a cask or other source of supply, and is provided with a valve 4-7. Said valve is supported on a member 4-8 of a compound lever, said member being fulcrumed at 4-9 in the receptacle 16. The other member 50 of said compound lever is fulcrumed at 51 in the receptacle, and is connected with the member 48 by a slot and pin, connection 52 .33. To one end of the lever member 50 is connected a float M- adapted to rise and fall with the liquid in the receptacle 1C. The arrangement is such that when the liquid falls in the receptacle below a given level, the alve at? is opened, admitting more liquid, and when a sufficient quantity has been admitted. the valve 4:7 is raised to shut off the entrance of more liquid.

In Figs. 2 and 3 l have shown the invention embodied in an appa al'us having four measuring receptacles arranged in pairs. but it is obvious that the number of receptacles may be varied to any extent required.

The measuring receptacles are provided with vent tubes M, which extend upwardly into the upper portion of the primary receptacle 1(3, and permit the escape of air displaced by the liquid entering the measuring receptacles.
